Conclusion
Lyme disease is caused by Borrelia burgdorferi, a spirochete bacterium that travels inside ticks and infects humans and other mammals. It goes through an incubation period, and the initial sign is a characteristic rash located in the site of the tick bite. Some patients do not notice the initial rash or do not remember being bitten by a tick. Thus, it is essential to consider Lyme disease’s diagnosis in patients with unexplained joint pain, headaches, malaise, neck stiffness, or fever of unknown origin.
